Question

Give theory as solution like background theory, what concepts will apply in this questions and theory in c++ language. Do not give source code just give theory. 

A teacher would like his students to play a small game. The rules of the game require that the students be divided into 4 groups (Red, Green, Blue and Purple) based on the following information for each student: 1. The roll number of the student - not more than 3 digits long and ranging between 1 and 400 2. The score of the student the last time he played this game (scores will be between 0 and 100) Your task is to write a program that automatically decides the new group of the student when the above information is entered. Your program must take into consideration the following rules for group assignment:
